You are flowing water onto a roof, you are using a master stream with a 11/2” tip. You flow water onto the flat roof for 12 minutes. How much weight in tons is on the roof?

11/2” tip – 600 gallons per min.
600 x 8.33 = 4998 lbs.
4998 x 12 = 59,976
59976 divided by 2000 = 29.988 tons

2

13/8” ground monitor with 400’ of 4” supply – what is the ep – convert to tons

nozzle = 80
appliance = 15
fl in 4” = 4.375 per 100’
4.375 x 4 = 17.5
ep = 112.5

3

Finding height where pressure is known.

Height = 2.3 X pounds pressure

4

NR for monitor with 13/8” tip with 4”

1.5 x 1.375 squared x 80
1.5 x 1.89 x 80
226.8

5

15/8” tip from deck gun on 2nd floor for 12 min – how many tons of water?

700gpm x12 min = 8400 gallons x 8.33 = 69,972 = 34.9 tons

6

10 x 20 x 8 tank – how many times can you fill big foot? 1600 cubic feet x 7.5 = 12000 gallons divided by 500

volume of a rectangle is LxWxH = cubic feet – 10x20x8 = 1600 cubic feet
gallons of water in a cubic foot = 7.5
1600 x 7.5 = 12,000 gallons divided by your 500 gallon tank = 24 times

7

Compound gauges measure what –

positive and vacuum pressures

8

Hydrant colors and gpm’s –

Class AA – light blue - 1500gpm or greater

Class A- green - 1000-1499 gpm

Class B - orange - 500 – 999 gpm

Class C - red - less than 500 gpm

9

While drafting, don’t let pressure drop below

50

10

3 things for relay pumping

quantity of water required, distance between water source and fire, size of the carrier, maximum distance that a pumper can deliver required quantities of water, max engine pressures, number of pumpers required for overcoming friction loss, topography

11

service pumping test

requires only 40 minutes of operation

12

certification test

3 hours

13

Max speed for slow moving vehicle – 25mph
Dmv handbook - you may not pass another vehicle which is moving slower than ____mph on a grade unless you can pass that vehicle at least _____mph faster than it is traveling and complete the pass in less than a _____mile

20mph, 10pmph, quarter mile

14
